The ruling class is most likely gonna put particles into the atmosphere to cool down the planet (With unforeseeable consequences for the rest of us of course) https://en.wikipedia.org/wiki/Stratospheric_aerosol_injection
They put "AI data-center" satellites into the orbit that so they can continue their pursuit of super-intelligent AI even after fucking the sky. In addition, the reentry of said satellites has the potential to destroy the ozone layer.

We are almost certainly gonna experience societal collapse within our lifetime.
Making those fuels request lots of energy (at least the energy that goes out), so unless that energy is produced with renewable resources, the CO2 footprint might actually be higher (as processes aren't 100% effective, making fuel takes more energy than the fuel has).
only possible way to make it worse is with space mining and manufacturers, but we're too far away from that.
Yeah thats true too, and... thats a lot of math to do, to try and estimate that.
And also yep, might make more sense if we actually had some kind of asteroid refining ability... but we do not.
Even if we did, it is much countless times easier not to fuck up the globe than having to rely on star Trek level technology to not go extinct.
